Application Of Barcode Technology In Libraries

APPLICATION OF BARCODE TECHNOLOGY IN LIBRARIES BY Dr. K. SATYANARAYANA LIBRARIAN KNOWLEDGE RESOURCE CENTRE GITAM UNIVERSITY VISAKHAPATNAM

History
super Markets in U.S.A
Bernard Silver and Norman Joseph Wood Land-1948
Commercial Application in 1960
plessey light pen system
Facts for Success
1.Bar code labels are cheap
2.It may be read with great accuracy, using fair priced reading devices
3.Standard symbologies have been developed
4.User friendly Technology

So many items in the market are using barcode technology
A Barcode is created with black bars followed by white spaces
So barcode is series if 1s and 0s representing numbers and letters
Depending on the nature of Information black bars and white spaces will be created by the software
INTRODUCTION

Typical structure of a barcode
Bi-directional Symbologies
Left to right or vice versa

Need for Barcode Technology in Libraries
Check in check out and Renewal of Reading material is a time consuming and laborious process
Arranging tickets in a classified order is time tedious job
Tickets trays occupy space
Reservation is a time consuming process
To know the status of book

TYPES OF BARCODES
ONE DIMENSIONAL
Consists of black bars and white spaces
Requires ordinary barcode scanners
TWO DIMENSIONAL
Composed of grid of light and dark modules
Requires 2D camera

Automotive industry applications
Chemical Industry Applications
Construction Industry Applications
Government Applications
Library Science Applications

Industries using barcodes (Contd):
Manufacturing applications
Package Industry Applications
Pharmaceutical Applications
Publishing Industry Applications
Retail/ whole sale Applications

CONTENT OF A BARCODE
Information of the product will be transmitted into numeric or alphanumeric form with the help of computer software.
The content and size of the bar code will depend on the data message, symbology, dimension, and bar code height.

CONTENT OF A BARCODE
The software will convert the information into black bands and white spaces.
While printing the bar code labels the stationery and environment in which the labels will be used should be taken into consideration

TYPES OF BARCODE PRINTERS
For printing the bar codes developed by the soft wares varieties of printers are available.
Dot Matrix Printer

Thermal Transfer Printer
Laser Printer

Ink Jet Printer

Important points in choosing the printer
Print quality
Connectivity
Speed
Easy to use
Size and weight
Environment
price

SCANNING AND DECODING
Scans and measures the presence and absence of light on the bars for reading the data
Starts and ends with specified marks on the barcode
Size is proportionate to the information available on the material

TYPES OF SCANNERS
1. CCD Scanners
2. Laser Scanners
3. Long range Hand held scanners
4. Omni directional Scanner
5. Fixed scanners.
6. Flat bed scanners

Auto ID in Libraries:
Flag character is to be used to avoid confusion between the user ID and document ID numbers
Barcode labels are to be laminated to protect them from the atmospheric changes

Application of barcode technology for stock verification
Data capture machine with hand held terminal
Dumping data on to the computer
Generation database with Accession numbers
Comparison with database generated by by the data of capture machine.
The mismatch will reveal the findings of the stock verification.
This will save a lot of time and laborious process in the stock verification.
This can be completed with in few days.

Benefits of barcode applications
ACCURACY:
accurate and reliable Human operator will commit undetected error for every 300 input.
Adopting bar coding technologies will improve input by factor of 10,000 times
ECONOMICS:
bar code labels can be produced in volumes, reducing the cost for user.

Benefits of barcode applications
SPEED:
Bar code or radio frequency tag carrying several hundred or even thousand characters of data can be captured while the object is on the move at high speed.
For example motorway toll, or firm objects on a moving conveyor belt
CONVENIENCE:
Auto ID technologies offer convenience and versatility
user friendly in operation
easily connected to wide range of computers and control equipment
